Bilateral renal cysts is a condition in which cysts develop on both of kidneys.Generally,the cysts are benign and cause no symptoms.However, as the cysts enlarge,the patients may experience a number of symptoms. If the symptoms of bilateral renal cysts occur, the patients have to seek for immediate treatment.
Bilateral renal cysts symptoms
In most cases, bilateral renal cysts do not cause symptoms.Some patients may not notice the disease through their life.However,in serious condition, the patients may experience the following symptoms.
Back and abdominal pain
As the cysts enlarge,the cysts will cause pressure against the adjacent kidney tissues and organs,resulting in back pain.Meanwhile,if the cyst or kidney is infected,the patients may experience very serious back and abdominal pain.Also,blood may be noticed in urine.Stretching of renal capsule is another attributable factor of back and abdominal pain in bilateral renal cysts.
High blood pressure
High blood pressure is a common symptom of bilateral renal cysts. As the cysts oppress against kidney tissues,it can lead to renal ischemia and anoxia.One of important kidney functions is to keep blood pressure. Renal ischemia and anoxia can affect the function, thus resulting in high blood pressure.
The presence of renal cysts also may cause infections,primarily in the kidneys or in the entire urinary tract. Difficult urination or painful urination, is the symptom mostly associated with urinary tract infections.
While kidney failure is rare in bilateral renal cysts, it occurs sometimes. As the cysts enlarge,they will replace more and more healthy kidney tissues and lead to renal ischemia and anoxia.The kidneys are used by the body to eliminate toxins from the person’s system.Kidneys essentially are filters that remove these toxins.When the kidneys fail to work, a large number of symptoms will occur.
